Vermont water-heater replacement touches three credentials: the OPR registration ('installation or repair of heating, plumbing … water … systems' is written into § 5501(b)), the DFS plumber license for the water side (26 V.S.A. ch. 39, subject to the owner-occupied/public-water scope exclusion) and the DFS electrician license for the electrical connection (26 V.S.A. ch. 15). Every claim sourced and dated.
Residential Contractor registration required above $10,000 (26 V.S.A. § 5501) — 26 V.S.A. § 5501(a) verbatim: 'A person shall register with the Office of Professional Regulation prior to contracting with a homeowner to perform residential construction in exchange for consideration of more than $10,000.00, including labor and materials.' § 5501(b): 'residential construction' means to build, demolish, or alter a residential dwelling unit, or a building or premises with four or fewer residential dwelling units, and includes interior and exterior construction, renovation, and repair; painting; paving; roofing; weatherization; installation or repair of heating, plumbing, solar, electrical, water, or wastewater systems.
